June 3, 1930. P. E. FENTON PIN FASTENER Filed May 28, 1929 Patented June 3, 1930 UNITED STATES PATENT' OFFICE PAUL E. IiENTON, OF THOMASTON, CONNECTICUT, ASSIGNOR T0 SCOVILL MANUFAC- TURING COMPANY, OF WATERBURY, CONNECTICUT, A CORPORATION OF CONNECT- ICUT :PIN FASTENEB Application filed May 28,

T he object ot this invention is to provide a pin for fastening a loose article to a fixed part, such as a cover for automobile seats and other upholstered parts.

In the present preferred embodiment of my invention, the pin is of the single-point type, with the head curved to iit a cap and bent eccentrically and terminating in a sharp point or spur which engages with a part to which the pin is applied in such way as to prevent accidental disengagement of the pin from such lixed part, and yet permitting desired disengagement by a tilting movement of the pin in an axial line, without the interposition or use of a tool, as I Will proceed now to explain more fully and finally claim. In the accompanyingy drawines illustrating the invention, in the severed figures of which like parts are sii'nilarly designated, Figure l is a front elevation; Fig. Q is a side elevation, and Fig. 3 is a rear elevation ot a capped pin-fastener. Fig. d is a front elevation ot the pin Without the Cap. Fig. 5 is a side elevation of the pin fastener applied to a 'fragment of an article shown in section. Fig. 6 is a cross-section taken on line 6-6 of Fig. 5, and Fig. 7 is a similar view illus tratingr the disengaring action.

qWithmit thereby limiting the utility of the invention. l will proceed to ex )lain more fully the construction of a pin astener designed for use in attaching covers to the desired parts, such as the seats, of an automobile.

The cap 1 may be of any usual or approved construction. ornamented or otherwise, and having the rim flange 2 which serves to connect with the pin. The pin has the sticking member 3, and a head composed of the arcuate or otherwise shaped portion 4 to engage With the closed-in dange Q, as shown in Figs. 2, 3, 5, (i and 'i'. and the reverted sharp point or spur 5 curved and extending rearwardly ot the cap and sticking' member. The top 6 of the pin next to the portion 4 is crooked laterally and rearwardly and to one side of the axis ot the sticking member 3, and overlies the spur 5. The end of the portion 4 crosses the sticking member 3, with its spur 5 on the side of the member 3 opposite to the portion 4.

1929. Serial No. 866,817.

The crooked portion 6 throws the sticking member 3 to one side ot the center ot the cap.

When the sticking'J member is stuck in a loose object, such as a seat cover, as indicated at 7, and then applied to a iXed object, such as an automobile part, indicated at 8, it is forced into it up to the crooked top 6 and the spur 5 enters the material in the opposite direction so that it opposes any accidental escape of the pin, as shown in Figs. 5 and 6. When it is desire-d to detach the pin, the cap may be tilted laterally from the side adjacent to the spur 5, using the sticking member as an axis, and the spur 5 is thereby automatically moved out of locking engagement with the article, as indicated in Fig. 7

The spur is so arranged as to pierce the material squarely, and lies at an angle of 9()O to the final restingr place of the material after it has been pushed down the entire length of the stickingA member, and this is a most effective nature of locking the pin in place, because it does not have a tendency of injuringV the material and is readily detachable without injury to the material and Without application of a tool. Merely tipping the cap sharply backwardly on the side opposite to the spur, removes the spur from the material and allows the Whole pin to be withdrawn easily and Without injury to the material.

Variations in the details of construction are permissible Within the principle of the invention and the scope ot the claims followlng.

What I claim is 1. A pin fastener, having a sticking member and a head, the head provided with a laterally crooked portion which serves to throw the sticking member oit' center, said head terminating! in a spur.

2. A pin fastener. havingT a sticking member and a head. the head provided with a latcralljY crooked portion which serres to throw the sticking member ntf center, said head terminating in a spur, the spurred end ot the head crossingV the stickingl member and located beneath the crooked portion.

3. A pin fastener, havingl a sticking' mehr ber and a head, the head provided with a crooked portion which serres to throw the sticking member otl' Center, said head terminating in a spur, and a Cap engaging a portion of the head and its spurred end, the Sticking member being eeeentrie with relation to the cap.

11:. A pin fastener, having a stieking member and a head. the head provided with a crooked portion which serves to throw the sticking member off renter, said head terminating in a spur, the spur extending rearwardl)v and adapted to engage an article to which the pin is applied, as theJ pin ie applied. and to be disengaged from sueh article by a tilting motion of the head on the axis ot the sticking member.

5. A pin faatener, having a Sticking member and a head, the top of the head heing crooked laterall)V and rearwardly and terminating at its bottom in an upwardly and rearwardly extending spur loeated beneath the crooked top and to one side of the Stieking member, so that the pin may be disengaged purposely from an article by a lateral tilting movement using the Sticking member as an axis.

(i. A pin fastener, having a Cap and a pin member Comprising a sticking member and a head engaged by Said Cap, said head havingr a eroolzed portion b v which the sticking' member is offset eceentrieallyv with relation to the cap. Said head terminating in a rearwardlj,Y and upwardly extending spur which en gages the article to which the pin is applied coineidentl;y with the sticking of the pin in said article. the spur being released from Snell engagement by a tilting motion of the head on an axis` coincident with the sticking portion.

T. A pin fastener, having a cap, and a pin comprising a sticking member and a` head engaged by Said cap, Said head haring a portion erooked off to one Side and also rearwardly. wherebyy the Sticking member is offset eecentrieally with relation to the Cap,y and Said head terminating in a rearwardly and npwardlv extending Spur which is arranged alongside the sticking member and is adapted to engage the artirle to which the pin is a1)- plied eoineidentlyr with the Sticking of the pin in said artirlefthe spur being released from snrh engagement by a tilting motion ot the head on an axie` coincident with the Stirking portion.

In testimony whereof I have hereunto set my hand this 27th day of May, A. D. 1929. PAUL E. FENTON.
